3) Retrieve and read the following article from the library (which is available online), and briefly answer the questions below: Emma Frankham, Christopher Jacobi, and Brandon Baidyanathan. Race, Trust in Police, and Mental Health Crisis Support Contexts: Understanding People in Their Social World (Summer, 2021) 20:3, pp. 60-62.

a) What is the basic hypothesis for these authors? Phrase their hypothesis in your own words.

b) Following up on your answer for part a), what are the independent and dependent variables for this hypothesis? What would be the appropriate test to use to determine if there is a statistically significant relationship between the two variables in this hypothesis? Explain why.

c) The 2nd figure on page 61 of the article shows that 70% of respondents who completely trust the police would call 911, while only 62% of those who trust the police a little would call 911. If the margin of error for these results is 3, construct 95% confidence intervals for each of these estimates, and interpret them. Is there a statistically significant difference between the two percentages?

d) The figure on page 62 shows that 68% of White respondents who completely trust the police would call 911, while 73% of Black or African America who completely trust the police would call 911. If the margin of error for these results is 3, construct 95% confidence intervals for each of these estimates, and interpret them. Is the difference statistically significant? Value: 7 points

I need help with a, b, c and d. I have included a link to the relevant article below.
